As part of sending an OAuth request to connect to Twitter, I have to
get a timestamp, as the number of seconds elapsed from Jan 01, 1970
(AKA the UNIX epoch). The simplest solution I could come with is the
following:
Remember you can do arithmetic with durations. I think this is even simpler:
T:\ftemp>xslt2 florent.xsl florent.xsl
<?xml version="1.0" encoding="UTF-8"?>1337617644.811
T:\ftemp>xslt2 florent.xsl florent.xsl
<?xml version="1.0" encoding="UTF-8"?>1337617649.455
T:\ftemp>type florent.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:my="urn:X-florent"
version="2.0">
<xsl:template match="/">
<xsl:value-of select="my:current-timestamp()"/>
</xsl:template>
<xsl:function name="my:current-timestamp" as="xs:string">
<!-- the UNIX epoch -->
<xsl:variable name="epoch"
select="xs:dateTime('1970-01-01T00:00:00Z')"/>
<!-- time since then -->
<xsl:variable name="diff" select="current-dateTime() - $epoch"/>
<!-- number of seconds -->
<xsl:sequence select="string($diff div xs:dayTimeDuration('PT1S'))"/>
</xsl:function>
</xsl:stylesheet>
T:\ftemp>
I hope this helps.
